Abstract (en)

[origin: EP0928885A2] Two shells (31,32) formed from plate parts are joined to one another and together form the walls (19) of the feed conduits, enclosing the catalyst medium (35) in cross-section. Each feed conduit has an inner wall (20) which in cross-section is enclosed by the shells and is separated from the shells by a free intermediate space (61), limiting a through passage for the exhaust gas. The two shells are welded to each other. Each shell for each feed conduit has a finger-shaped section (32b). Intermediate spaces are present between the finger-shaped sections belonging to the same shell. The shells in cross-section enclose an entry inner wall (41), which has an end and away from this limits an inner space area and/or through passage for the exhaust gas.
